After installing update v 33 for Desktop 2023 we can no longer access our mapped drives - which is where we backup our company file.  QB in it's infinite wisdome has apparently deemed it only appropriate to back a file up to the machine on which it lives.  So annoying.  The online upload has never worked.  And this was after trying to do the update and have it hang at writing registry values.  Dis a bit of research and discovered that it is a known issue (but Intuit doesn't let you know there will be an issue, you have discover it yourself and search out the answer yourself).
